The price of road poles is not the same for every manufacturer. What are the standard technical requirements for road poles? 1. The light pole is a single-armed light pole. The center of the lighting fixture is 8M, 7M, and 6M from the ground. 2. The lighting pole material adopts Q235A steel (silicon content is not higher than 0.04%) to be formed into a cone at a time, the thickness is 3.8-4mm (the thickness does not include the thickness of the galvanized layer), the lighting pole diameter is 60mm, and the lower diameter is 180mm. Outside of the length of 1.4M.

3, the lighting pole is automatic argon arc welding, the surface is smooth, the surface of the rod body is not uneven, uneven, no traces, no apparent defects, the linear error of the light pole center line does not exceed 0.02% of the rod length. The lighting pole adopts internal and external hot-dip galvanized anti-corrosion treatment. The galvanized layer is not less than 75um, and the service life is more than ten years. 4. The pole door adopts plasma cutting, the bottom is 500mm away from the flange, and the welding boss at the door opening has a reasonable operation space.
